How quickly could a massive Antarctic glacier collapse?
The collapse of the Thwaites Glacier in West Antarctica could significantly affect global sea levels. It already drains an area roughly the size of Britain or Florida state, accounting for around 4% of global sea-level rise - an amount that has doubled since the mid-1990s.
The US National Science Foundation (NSF) and UK’s Natural Environment Research Council (NERC) are teaming up to study it as part of a £20 million research collaboration.
On the stand meet the most famous name in marine robotics Boaty McBoatface, an Autosub Long Range (ALR). Developed at the National Oceanography Centre in Southampton (UK), it will be able to travel deep beneath the ice sheet to collect important new data.
